An engine operates on the theoretical diesel cycle with a compression ratio of 15. The heat is added for 10% of the stroke. The pressure and temperature of the air at the beginning of compression are 98 kPa and 17C. Determine: 1.The cut-off ratio, 2.The pressure and temperature at the end of each process, 3.The amount of heat added, 4.The thermal efficiency of the cycle, and 5.The volume flow rate of air, measured at the beginning of compression, needed to produce 200 kW
